HPV is believed to cause cancer by integrating its genome into nuclear DNA. Some of the early genes expressed by HPV, such as E6 and E7, act as oncogenes that promote tumor growth and malignant transformation. [17] HPV genome integration can also cause carcinogenesis by promoting genomic instability associated with alterations in DNA copy ...
HPV+OPC presents in one of four ways: as an asymptomatic abnormality in the mouth found by the patient or a health professional such as a dentist; with local symptoms such as pain or infection at the site of the tumor; with difficulties of speech, swallowing, and/or breathing; or as a swelling in the neck (if the cancer has spread to lymph nodes).

When used without context, it frequently refers to infections (squamous cell papilloma) caused by human papillomavirus (HPV), such as warts. Human papillomavirus infection is a major cause of cervical cancer, vulvar cancer, vaginal cancer, penis cancer, anal cancer, and HPV-positive oropharyngeal cancers.
Forcing the cell into the S phase of the cell cycle could cause the cell to become transformed. [27] Human papillomavirus infection is a major cause of cervical cancer , vulvar cancer , vaginal cancer , penis cancer , anal cancer , and HPV-positive oropharyngeal cancers .

Human papillomavirus (HPV)-associated oropharyngeal cancer awareness and prevention is a vital concept from a public and community health perspective. HPV is the sexually transmitted virus that is known to be the cause of genital warts. There are currently more than 100 different strains of HPV, half of which can cause genital infections. [1]
